Application filed February 27, 1914. Serial No. 821,508.

To all whom it may concern Be it known that I, Burns KING, a citizen of the United States, residing at Plainville, in the county of Norfolk and State of Massachusetts, have invented a new and useful Improvement in Extensible Bracelet-Chains, of which the following is a specification.

My invention relates to the construction of the extensible link of a bracelet chain whereby an improved manufacture is pro duced which has desirable points of improvement.

In the accompanying drawing :-Figure 1 represents an edge View of a series of assembled links. Fig. 2 represents a plan view of the same. Fig. 3 represents an axial enlarged longitudinal section of the outer and inner members. Fig. 4represents aplan view of the inner member and section of the outer member. Fig 5 represents a transverse section taken in the line 5, 5, of Fig. 3. Fig. 6 represents the plan view of the outspread blank from which the outer member of the link is formed. Fig. 7 represents an edge view of the same when folded to make the outer member of the link. Fig. 8 represents a plan view of-the same. Fig. 9 represents a forward end view of Fig. 7. Fig. 10 represents a'plan View of the inner member of the link. Fig. 11 represents an edge view of the same. Fig. 12 represents the separate outer member of a modification without the inner sliding inner member or the spring, the said outer member being made in two parallel parts. Fig. 13 represents a longitudinal division of the same with the inner parts. Fig. 14 represents a side view of the inner part without the spring. Fig. 15 represents a section as taken in the line 15, 15, of Fig. 13.

In the drawing, A, A, A, Fig. 1 represent the assembled extensible links of a bracelet chain, and B, B, the connecting intermediate links by means of which the said extensible links are connected.

The outer member a, of the link is formed of a flat piece of sheet metal cut out as shown in Fig. 6, and then folded as shown in the edge view Fig. 7 thus forming the bend b for holding a connecting intermediate link and the inwardly directed pr0 jections c, c, for entering the end of the acting spring (Z by means of which the folded sides 6, c, of the outer member are held together and prevented from springing apart, the plan view of the said outer member being shown in Fig. 8, while the view of the open end 7 is shown in Fig. 9, as being turned at a quadrant from axial position of Fig. 8.

In Fig. 10 a plan view of the sliding inner member of the link is represented the curved edge view of the said member being represented in Fig. 11, and in the case of this member both arms 9, 5/, are folded lengthwise and provided with inwardly turned projections 71, 72, which by entering the end of the spring 03 as shown in Fig. 4 serve to hold the said arms 9, 9, together, the bend 0 serving to hold an intermediate link B of the chain.

A modification is shown in Figs. 12, 13, 14 and 15, in which the outer member is made in two parallel parts i, c, which are connected to each other at one end by means of the soldered pin 7' and have attached to their opposite ends the inwardly directed spurs 7s, 7s. The sliding inner member m, is shown separate in Fig. 14 and the combination of the outer and inner members and the spring 7% is shown in Fig. 13, with the front side of the outer member removed, and Fig. 15 shows a transverse section of the complete link taken on line 15, 15, of Fig. 13.

I claim as my invention:

In a link, an outer member having open sides and a closed end, a pair of inwardly extending projections at the opposite end thereof closing said opposite end, a sliding inner member having a pair of inwardly extending projections which latter are disposed adjacent the opposite end of the outer member, and a spring insertible bodily and lengthwise through either side of the outer member while the ends of the latter are closed, the ends of said spring embracing the respective projections of the inner and outer members.
